Facile synthesis of Co3O4 mesoporous nanosheets and their lithium storage properties

• Co3O4 mesoporous nanosheets have been synthesized by a facile method.
• The morphology and microstructure of the products are thoroughly characterized.
• Co3O4 mesoporous nanosheets delivered reasonable electrochemical performance.
• The good electrochemical performance can be attributed to the special structural nature.

Co3O4 mesoporous nanosheets (MNSs) were successfully synthesized by a facile direct precipitation method and subsequent annealing process. When used as the anode materials of Li-ion batteries, the as-prepared sample delivered reasonable capacity, good cycling stability and rate capability, which may be attributed to the mesoporous structural nature.
